A JavaScript object can be of great help when you need to pass multiple values to a Modal Window. E.G.
var objArgs = new Object();
objArgs.Value1 = "Value 1";
objArgs.Value2 = 2;
var modalWindowFeatures = 'dialogHeight:600px;dialogWidth:600px;scroll:no;status:no;resizable:no';
url = 'relative/path/to/page';
var returnValue;
returnValue = window.showModalDialog(url,objArgs,modalWindowFeatures );
"Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression"
As the error message suggests , this normally occurs when you are assigning a T-SQL variable a value within sql query and the query is returning more that one rows e.g.
Declare @var1 nvarchar(50)
' select @var1=name from table1'
Putting 'top 1' can resolve the problem in many cases ( do check the business logic aspects):
' select top 1 @var1=name from table1'
other day I had to install Visual studio.NET 2003 on my system, the problem was I had Visual Studio 2005 and 2008 with framework 2.0 and 3.5 and I did not have .NET 1.1 on it.
There were two suggetions from ppl at work:
- Install .NET framework 1.1 and load project in VS 2005
- You will need to Un install VS 2005 and 2008 and then install VS.NET 2003
After googling a little first idea did not seem workable and I was not ready to follow the second option of starting all over. Half hour down I found a solution:
The trick is to install .NET framework 1.1 separately first and then run Visual studio 2003 installer.
-- Follow UP
VS 2003 is working fine, VS 2005 and SQL Server 2005 prompt an error on start "unable to load file, this error could not be resolved, Please reinstall the application". It seems to work fine though.
If you have a gridview/repeater control or other tabular data within a div, scroll bar appears when height of data gets bigger than that of DIV.
If you want to scroll down to a certain position, you can use 'Element.scrollTop' property in Javascript:
document.getElementById(divWithScroll').scrollTop = PixelsToScroll;
Calculating the PixelsToScroll may vary depending on scenerio,
In my case, I wanted to scroll down to a selected row within Repeater control. Row was selected using RadioButton and page was reloaded on selection of RadioButton. So, I saved the SelectedItem.ItemIndex in Repeater_ItemDataBound in a hidden field and using the value in Javascript like following:
PixelsToScroll = SelectedItem * 22;
where 22 is height of table row
Problem: Say you have two Grid View controls on one page, each grid view has a TexBox and a 'search' button above it
TextBox1 btnSearch1 TextBox2 btnSearch2
Now if you press 'Enter' key in TextBox1, it will trigger btnSearch1_click event and when you press 'Enter' key in TextBox2, it still triggers btnSearch1_click
Solution: Add asp.net Panel tag and set DefaultButton property.
<asp:Panel ID="pnlSearch2" runat="server" DefaultButton="btnSearch2">
TextBox2 btnSearch2
</asp:Panel>
I had a Repeater control within a div. Now when there were more records than visible within height of DIV a scroll bar appear. But, when user scrolls down, the headings ( within HeaderTemplate) would go up and not be visible.
After googling a little, I was able to find the solution on code project:
http://www.codeproject.com/KB/webforms/DataGridFixedHeader.aspx
In my case though I had a 'tr' element within 'HeaderTemplate' element ,so I applied it to like:
<tr class="ms-formlabel DataGridFixedHeader " >
Limitation:
It worked fine in IE 7, but in IE 6 the background image, if you have any in css, would disappear on scrolling.
It s really easy to debug a SQL sever stored procedure in Visual Studio, here are the steps:

I had to update value from a staging table( this might be a temp table ) into another database table. Here is how I did it using a inner join in the Update statement.
UPDATE Table1
SET Table1.Field1 = StagingTable.Field1
FROM Table1 INNER JOIN StagingTable ON Table1.Field2 = StagingTable.Field2
You can also add a where clause to this SQL:
WHERE StagingTable.Field3 IS NOT NULL
---------------------------------------------------------------------
Same way we can use JOINs in insert and delete statements
